I have a question to ask you guys. I have a JBL system with RD4 in my car, problem is everytime when I start the engine, there are some strange noises come from the speakers, but it only lasts like 2 secs and it goes away.
I just did the "1000 miles" service for my car yesterday. So I aksed them about this small problem, after the investigating surprisingly they told me there may be a fault in the RD4 head-unit. So they have to sent the unit back to peugeot to do the repairing. And they are not sure how long it's gonna take.

Does anybody have the same problem out there?
PS: Is there anyway I can change the original CD unit to other units like Kenwood, Sony ... ... ? And I won't lost the control of the trip computer.
